Enhanced production of bioactive isoprenoid compounds from cell suspension cultures of Artemisia annua L. using β-cyclodextrins.

ABSTRACT: Plant cell cultures as valuable tools for the production of specific metabolites can be greatly improved by the application of elicitors including cyclodextrins (CDs) for enhancing the yields of the desired plant compounds. Here the effects of 2,6-dimethyl-β-cyclodextrins (DIMEB) on the production of carotenoids and quinones from Artemisia annua L. cell suspension cultures were investigated. The addition of 50 mM DIMEB induced an early increase of intracellular carotenoid and quinone contents, which could be observed to a higher extent for lutein (10-fold), Q9 (3-fold) and Q10 (2.5-fold). Real Time PCR analysis revealed that the expression of 1-deoxy-d-xylulose-5-phosphate reductoisomerase (DXR) gene in DIMEB treated cell cultures after three days was 2.5-fold higher than in untreated samp
